[0037] In an optional implementation manner of the embodiment of the present invention, Fig.11 As shown, the material collecting mechanism includes: a material receiving trough 35, a discharging conveyor belt 36, a servo motor IV 37, and a baffle 38; the bracket of the discharging conveyor belt 36 is fixedly installed on the material receiving trough 35, and the motor gear of the servo motor IV 37 is meshed with the transmission gear inside the discharging conveyor belt 36, thereby driving the discharging conveyor belt 36 to rotate; the baffle 38 is fixedly installed on the discharging conveyor belt 36, and the cut sealing short strips can be dropped onto the material receiving trough 35 through the baffle 38.

[0039] In an optional implementation manner of the embodiment of the present invention, Figure 1 As shown, the reciprocation of the rear conveying path 8 and the front conveying path 9 in the horizontal direction is synchronized with the reciprocation of the blade 7 in the horizontal direction.

[0040] Working principle: When the present invention is in use, the cam 2 drives the upper and lower blades 7 to achieve a high-speed production line speed. The reciprocating speed of the rear conveyor 8 and the front conveyor 9 is accelerated synchronously with the blade 7, so that the blade 7 remains relatively still with the sealing strip when cutting the sealing strip, achieving online cutting of ultra-short products with a length of 100 to 300 mm, and the cutting is smooth. When the present invention is in use, the sealing strip is cut and formed in one step, saving the secondary processing process, reducing the workshop space occupied by the material receiving and secondary transfer storage, reducing the waste of raw materials in the secondary processing process, and saving costs;

[0041] Specifically, when the present invention is used, the sealing strip is inserted into the guide mechanism. Before the insertion, the guide mechanism is adjusted according to the parameters of the sealing strip. The knob I 31 is turned to adjust the spacing between the vertical guide wheels 32 to adapt to the width of the sealing strip. The knob II 34 is turned to make the upper horizontal guide wheel 33 slide in the extension bracket slide groove of the import rack 29, thereby adjusting the spacing between the horizontal guide wheels 33 to adapt to the thickness of the sealing strip, so that the sealing strip maintains stable transmission when entering. Next, the servo motor II 19 and the servo motor III 20 are started and rotated in opposite directions, thereby driving the upper conveyor belt 17 and the lower conveyor belt 18 to rotate, driving the sealing strip to be transmitted to the rear conveyor 8 and the front conveyor 9;

[0042] The next step is cutting. The servo motor I13 is started, and the pulley group 14 is driven to rotate through the long belt 15, thereby driving the cam 2 to rotate. The upper cam 2 rotates in opposite directions to the lower cam 2, so that the upper and lower beams 3 rotate symmetrically in circles. When the upper and lower blades 7 are rotated to contact, the sealing strip is cut. The rotation speed of the cam 2 can be controlled by the program to increase the cutting speed. When accelerating, the reciprocating speed of the rear conveyor 8 and the front conveyor 9 is accelerated synchronously with the blade 7. In this way, the blade 7 remains relatively still with the sealing strip when cutting the sealing strip, and the sealing strip can still be cut very neatly, thereby increasing the speed limit of the equipment and making the cut sealing strip shorter. The cut sealing strip is then transported outward through the discharge conveyor 36, and falls onto the receiving trough 35 under the action of the baffle 38 for collection.
